Could you review a fix for jdk8u, please?
The fix for 7162125  enabled font tables processing on OSX. However there is a lack of support for RTL languages in ICU layout engine. Quote from ICU guide: “…The AAT processing in the LayoutEngine is relatively basic as it only applies the default features in left-to-right text. This processing has been tested for Devanagari text. Since AAT processing is not script-specific, it might not work for other scripts…”, more details at http://userguide.icu-project.org/layoutengine
As a result all RTL languages on OSX are incorrectly laid out, (i.e. the letters are reversely presented).
Skip font tables for RTL languages on OSX platform.
